Rev 1.0, August 7, 2008 Page 3 of 12 SL15316 General Description Programmable CL (Crystal Load) The primary source of EMI from digital circuits is the system clock and all the other synchronous clocks and control signals derived from the system clock. The well know techniques of filtering (suppression) and shielding (containment), while effective, can cost money, board space and longer development time. The SL15316 provides programmable on-chip capacitors at XIN/CLKIN (Pin-3) and XOUT (Pin-2). The resolution of this programmable capacitor is 6-bits with LSB value of 0.5pF. When all bits are off the pin capacitance is CXIN=CXOUT =7.0pF (minimum value). When all bits are on the pin capacitance is CXIN=CXOUT=38pF (maximum value). The values of CXIN and CXOUT based on the CL (Crystal Load Capacitor) can be calculated as: CXIN=CXOUT=2CL-CPCB. Refer to the Page-10 for additional information on crystal load (CL). A more effective and efficient technique to reduce EMI is Spread Spectrum Clock Generator (SSCG) technique. Instead of using constant clock frequency, the SSCG technique modulates (spreads) the system clock with a much smaller frequency, to reduce EMI emissions at its source: The System Clock. The SL15316 is designed using SpectraLinear proprietary phase-locked loop (PLL) and Spread Spectrum Technologies (SST) to synthesize and modulate (spread) the system clock such that the energy is spread out over a wider bandwidth. This reduces the peak value of the radiated emissions at the fundamental and the harmonics. This reduction in radiated energy can significantly reduce the cost of complying with regulatory agency requirements and improve time-tomarket without degrading system performance. The SL15316 operates from 3.3V to 2.5V power supply range. Separate VDDO power supply is provided for thre (3) output clock drivers. The supply voltage on these pins could be 3.3V to 25V or 1.8V as long as VDDO≤VDD condition is met. The SL15316 is available in 16-pin TSSOP package with Commercial Temperature range of 0 to 70°C and Industrial Temperature range of –40 to 85°C. Input Frequency Range The input frequency range is from 8.0 to 48.0 MHz for crystals and ceramic resonators. If an external clock is used, the input frequency range is from 3 to 166 MHz. Output Frequency Range and Outputs Up to five (5) outputs can be programmed as SSCLK or REFCLK. SSCLK output can be synthesized to any value from 3 to 200 MHz with spread using input frequency. The spread at SSCLK pins can be stopped by SSON# input control pin, If SSON# pin is HIGH (VDD), the frequency at this pin is the synthesized to the nominal value of the input frequency and there is no spread. REFOUT is the buffered output of the oscillator and is the same frequency as the input frequency without spread. However, REFOUT value can also be divided by using the output divider. The SSCLK is the programmed and synthesized value of the input clock. The remaining SSCLKs could be the same value providing fanout of up to 5 or the frequency can be divided from also 2 to 32. In this case, the spread % value is the same as the original programmed spread % value. By using only first order crystals, SL15316 can synthesize output frequency up to 200 MHz, eliminating the need for higher order Crystals (Xtals) and Crystal Oscillators (XOs). This reduces the cost while improving the system clock accuracy, performance and reliability. Rev 1.0, August 7, 2008 In addition, if an external clock is used, the capacitance at Pin-4 (XIN/CLKIN) can programmed to control the edge rate of this input clock, providing additional EMI control. Programmable Modulation Frequency The Spread Spectrum Clock (SSC) modulation default value is 31.5 kHz. The higher values of 60, 90 and 120 kHz can also be programmed. Less than 25 kHz modulation frequency is not recommended to stay out of the range audio frequency bandwidth since this frequency could be detected as a noise by the audio receivers within the vicinity. Programmable Spread Percent (%) The spread percent (%) value is programmable from +/0.125% to +/-2.5% (center spread) or -0.25% to -5.0% (down spread) for all SSCLK frequencies. It is possible to program smaller or larger non-standard values of spread percent. Contact SLI if these non-standard spread percent values are required in the application. SSON# or Function Select (FS) The SL15316 Pins 7, 12 and 15 could be programmed as either SSON# to enable or disable the programmed spread percent value or as Frequency Select (FS). If SSON# is used, when this pin is pulled high (VDD), the spread is stopped and the frequency is the nominal value without spread. If low (GND), the frequency is the nominal value with the spread. If FS function is used, the output pins could be programmed for different set of frequencies or spread % as selected by FS. SSCLK value can be any frequency from 3 to 200MHz, but the spread % is the same percent value. REFOUT is the same frequency as the input reference clock or divide by from 2 to 32 without spread. The SL15316 allows a fan-out of up to 5 clocks, meaning that Pins 7, 11, 12, 13 and 15 can be programmed to the same frequencies with or without spread. Power Down (PD#) or Output Enable (OE) The SL15316 Pins 7, 11, 12, 13 and 15 could also be programmed as either PD# or OE. PD# powers down the entire chip whereas OE only disables the output buffers to Hi-Z. Spread Spectrum Clock Modulation Frequency The modulation frequency of spread spectrum clock can be programmed from 25 to 120kHz.

Place the capacitor on the component side of the PCB as close to the VDD and VDDO1/2 pins as possible. The PCB trace to the VDD pin and to the GND via should be kept as short as possible Do not use vias between the decoupling capacitor and the power supply pins. Series Termination Resistor: A series termination resistor is recommended if the distance between the outputs (SSCLK or REFCLK pins) and the load is over 1 ½ inch. The nominal impedance of the SSCLK output is about 30 Ω. Use 20 Ω resistor in series with the output to terminate 50Ω trace impedance and place 20 Ω resistor as close to the SSCLK or REFCLK outputs as possible. Crystal and Crystal Load: Use only parallel resonant fundamental crystals. DO NOT USE higher overtone crystals. To meet the crystal initial accuracy specification (in ppm); the internal on-chip programmable capacitors PCin and PCout must be programmed to match the crystal load requirement. These values are given by the formula below: PCin(pF) =PCout(pF)= [(CL(pF) – Cp(pF)/2)] x 2 Where CL is crystal load capacitor as given by the crystal datasheet and Cp(pF) is the compensation factor for the total parasitic capacitance at XIN or XOUT pin including PCB related parasitic capacitance. As an example; if a crystal with CL=18pF is used and Cp=4pF, by using the above formula, PCin=PCout=[(18-(4/2)] x 2 = 32pF. Programming PCin and PCout to 32pF assures that this crystal sees an equivalent load of 18pF and no other external crystal load capacitor is needed. Deviating from the crystal load specification could cause an increase in frequency accuracy in ppm. Refer to the Table 5 for the recommended crystal specifications.
